South Korean actor Lee Kwang Soo has opened up about exposing a little too much for his new web-drama. The 31-year-old actor is the lead in KBS 2TV's show, The Sound of Your Heart.

Kwang Soo will be playing the main character, Jo Suk, who is a cartoonist and Jung So Min will be playing his girlfriend, Ae Bong. This web-drama is an adaptation of the popular webtoon of the same name.

Song Joong Ki's best friend revealed how he prepared himself for the nude scenes. He said: "I liked the webtoon a lot so I felt a little intimidated. I talked a lot with the director before the filming and received lots of support while filming as well."

He added: "The director told me before we started that there was a little nudity so I tried to prepare my mind. I assumed it would be my upper half, but it turned out to be my lower half. When I found that out, I had to prepare my body instead."

Meanwhile, in the drama, Kim Dae Myung will be playing Kwang Soo's older brother, Jo Joon, and Kim Byung Ok and Kim Mi Kyung will be playing Kwang Soo's parents.

The Sound of Your Heart will air every Monday through Naver TV Cast from 7 November.
